Vulnerability from osv_openeuler – Published: 2023-03-10 11:05 – Updated: 2026-08-06 11:05 – Source website

Summary

rubygem-activesupport security update

Details

A toolkit of support libraries and Ruby core extensions extracted from the Rails framework. Rich support for multibyte strings, internationalization, time zones, and testing.

Security Fix(es):

A regular expression based DoS vulnerability in Active Support <6.1.7.1 and <7.0.4.1. A specially crafted string passed to the underscore method can cause the regular expression engine to enter a state of catastrophic backtracking. This can cause the process to use large amounts of CPU and memory, leading to a possible DoS vulnerability.(CVE-2023-22796)

Severity

7.5 (High)
